// 此示例使用 DsNWind 示例数据库创建 PDF 发票，
// 并将根据 ZUGFeRD 1.x 标准规则创建的 XML 文件附加到其中。
//
// ZUGFeRD 是基于 PDF 和 XML 文件格式的德国电子发票标准。
// 它准备改变发票的处理方式，并可供任何类型的企业使用。
// 它将使发件人和客户的发票处理更加高效。
// 详细信息请参见什么是ZUGFeRD？ 。
//
// 此示例使用 ZUGFeRD-csharp 包
// 创建附加到发票的 ZUGFeRD 兼容 XML。
//
// 有关使用 GcDocs.Html 将 HTML 渲染为 PDF 的详细信息，请参阅HelloWorldHtml。
